I used to have a crx and it is a very popular swap for 88-91s, but i was wondering if it would work in a ek? I saw on for cheap, i know all the info on b-series motors(b16, b17, b18) but was curious about the ZC.

 

It will work, but if you want to go cheap I would recommed a b18b or b20z. Those cost more then the ZC but you have many more mod options, and a better base to start from.
